Pyruko: The New Logic Puzzle That's Not for Squares

by Jack Lyons

Pyruko is a two-dimensional logic puzzle that can be transformed into a three-dimensional puzzle. The puzzle consists of 36 individual triangles that form four larger triangles. The directions are fill in the grid so that each of the four triangles that make up the main triangle contains the numbers one through nine. Additionally, when the grid is folded into a pyramid (or "tetrahedron" for all the math-whiz types) each of the four axes must also contain the numbers one through nine. A thoroughly original variation on the popular puzzles that dominate the market, the power of Pyruko will delight and enthrall game lovers of all ages.
